Signals of Neutralino Dark Matter from Earth and Sun

Abstract

We evaluate the fluxes of up--going muons detectable in a neutrino telescope and due to the annihilation of relic neutralinos in the Earth and in the Sun, taking realistically into account the fact that neutralinos might provide only a fraction of the local (solar neighbourhood) dark matter (DM). We determine the relation between the exposure $At$ of the neutrino telescope ($A$ being the telescope area, $t$ the live time) and the explorable range of the neutralino mass and composition, when the signal--to--background ratio is optimized by an appropriate angular selection.
